Baseball bat frame



FIG. 1 is a perspective view of a baseball bat frame, showing my new design;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a top plan view thereof;

FIG. 4 is a bottom plan view thereof;

FIG. 5 is a rear elevational view thereof; and,

FIG. 6 is a left-side elevational view thereof, the right-side elevational view being a mirror image thereof.

The broken lines showing a team logo, mat cut-out, player number, and text on one of the bats in FIGS. 1 and 2 depict environmental matter and form no part of the claimed design. 

I claim the ornamental design for a baseball bat frame, as shown and described.
